Embodiment 1

[0030] A method for manufacturing human body bionic blood vessels by using 3D printing combined with mold turning process, comprising the following steps:

[0031] (1) Use medical drawing software to extract medical imaging blood vessel data. Medical data will be obtained through CT / MRI or blood vessel B-ultrasound to obtain medical DICOM data, and medical software such as Mimics will be used to extract blood vessel digital data to form computer three-dimensional image data;

[0032] (2) Use the 3D image data of blood vessels to use computer 3D drawing tools (maya, 3Dmax, UG, Solidworks, Zbrush) and other software to create a 3D image of blood vessels to form the structure of the vascular lumen, the structure of the vascular wall, and the shape of the blood vessel; use engineering reverse The software performs three-dimensional blood vessel wall thickening, optimization and other operation steps, and divides the outer wall and inner wall of the blood vessel to form a detachable...

Embodiment 2

[0044] A method for manufacturing human body bionic blood vessels by using 3D printing combined with mold turning process, comprising the following steps:

[0045] (1) Use medical drawing software to extract medical imaging blood vessel data. Medical data will be obtained through CT / MRI or blood vessel B-ultrasound to obtain medical DICOM data, and medical software (Mimics) will be used to extract blood vessel digital data to form computer three-dimensional image data;

[0046] (2) Change the 3D image data into an STL format file that can be recognized by the 3D printer through a computer 3D drawing tool (maya);

[0047](3) Import the STL format file into the 3D printing equipment, and print the vascular mold through the 3D printing equipment. The printing materials of the vascular inner mold and the outer vascular mold include medical polypropylene or ethylene, and the printing accuracy is 0.02㎜. The inner mold and the outer mold retain the cavity gap and complete structural ...

Embodiment 3

[0056] A method for manufacturing human body bionic blood vessels by using 3D printing combined with mold turning process, comprising the following steps:

[0057] (1) Use medical drawing software to extract medical imaging blood vessel data. Medical data will be obtained through CT / MRI or blood vessel B-ultrasound to obtain medical DICOM data, and medical software (Mimics) will be used to extract blood vessel digital data to form computer three-dimensional image data;

[0058] (2) Change the three-dimensional image data into an STL format file that can be recognized by the 3D printer through a computer three-dimensional drawing tool (UG);

[0059] (3) Import the STL format file into the 3D printing equipment, and print the vascular mold through the 3D printing equipment. The printing materials of the vascular inner mold and the outer vascular mold include medical polypropylene or ethylene, and the printing accuracy is 0.03㎜. The inner mold and the outer mold retain the cavity ...

Abstract

The embodiment of the invention discloses a method for manufacturing a bionic blood vessel of a human body by combining three-dimensional (3D) printing and a model turning process. The method comprises the following steps of (1) using a medical software for extracting blood vessel digitized data, and forming computer 3D image data; (2) converting the 3D image data into an standard template library(STL) formatted file; (3) importing the STL formatted file into a 3D printing device, and printing a blood vessel model; (4) polishing the blood vessel model; (5) adopting a model turning process formanufacturing a paraffin internal model; (6) filling the inner wall and the outer wall of the blood vessel model; and filling a blood vessel structure of the blood vessel model; (7) standing for 12 to 48 hours, and then accomplishing silica gel curing; and (8) disassembling the blood vessel model, and obtaining the bionic blood vessel of the human body. The method for manufacturing the bionic blood vessel of the human body by combining 3D printing and the model turning process provided by the invention solves the problems that the wall thickness of the blood vessel prepared by an existing method is non-uniform, and the blood vessel is lack of a true human anatomy structure blood vessel chamber structure and a wall thickness structure.

Description

technical field [0001] The invention relates to a method for manufacturing a human body structure blood vessel, in particular to a method for manufacturing a human body bionic blood vessel by using 3D printing combined with a mold-turning process. Background technique [0002] The number of intravenous punctures in China exceeds tens of billions each year, and venipuncture is dominant in nursing skills. The current intravenous injection education products have simple vascular structures, "general" vascular outlines, weak human body structure, and cannot show the structure and shape of blood vessels in various parts. , the current market lacks a real puncture product that imitates the human vein structure. [0003] Cardiovascular disease is the disease with the highest incidence and mortality rate in the world. The mortality rate of cardiovascular disease occupies the first place in China. The role of venous catheter puncture in cardiology is becoming more and more important....
